Can your manual boost controller perform as well as an electronic
A: Yes, and in most instances it will
spool the turbo faster than many of the expensive electronic
units. As much as 600 rpm faster to full boost.
Can I have cockpit control of my boost with a manual controller?
A: Yes, we now have available 3 new
kits to control boost from inside the car. The Evolution RX,
The Evolution, and an add-on Cockpit Controller Cable that
fits all previous model Hallman boost controllers, except
the ES kit.
What if I want to turn my boost up or down for different gas
(pump vs. race)?
A: We recommend that after you get boost
set for where the car performs well on pump gas that you put
an index mark at tdc on the adjustment knob. Then after you
set your boost for race gas, do the same thing so that you
can easily adjust the knob for the boost level that you want.
Can I just install a boost controller and turn up the boost
A: In most instances, no. We recommend
that you have a performance cat-back exhaust system and a
low restriction air filter. These mods will insure that when
boost is added your motor can breath to get the air in and
the exhaust out.
Is the stock boost gauge in the car accurate?
A: No. We recommend that you have an
aftermarket gauge to properly know where your boost is at
stock and to accurately know how much you are increasing it.
Is your boost controller a bleeder valve?
A: No. A bleeder valve type controller
creates a leak in the line running to the wastegate. The larger
the leak the more boost you get, but the larger the leak the
more turbo lag you will get as well. Our kit blocks the signal
before the wastegate until the internal spring pressure of
the valve is overcome. At this point the signal can reach
the wastegate and open it. Since the internal spring pressure
is adjustable, you can increase boost. Since there is no leak
with this system the turbo will spool as quick as it can for
Can I lower my boost with a boost controller?
A: No. With any boost controller you
can only raise boost above what the factory actuator is set
How much horsepower can I gain from raising my boost?
A: With the addition of a performance
cat-back exhaust and a low restriction air filter you can
have up to a 50 hp gain depending on the size of the factory
turbo. With a larger turbo(s), a built motor and proper fuel
management it is not out of the question to double or even
triple the factory horsepower.
Can weather changes affect a manual boost controller?
A: Bleeder valve type boost controllers
are very susceptible to temperature and barometric changes
which cause changes in boost levels. Our boost controller
is not a bleeder valve, since it controls boost by internal
spring pressure and that spring pressure is not affected by
weather changes. Therefore boost will not be affected by weather
Will your boost controller fix problems I am having with my
A: That depends what is causing the
problem. If the problem stems from the current controller
then yes, it can fix the problem. It will not fix boost creep,
which is when the wastegate cannot vent enough exhaust to
control boost. This problem is where boost continues climbing
past where you have set it. Another problem it will not fix
is when the turbo is physically too small to hold higher boost
levels in the upper rpm's. This is where boost will reach
the level that you set it to and then start to fall off as
If I were to purchase an electronic unit, which one would
A: If you want an electronic unit, we
would recommend the HKS EZ. It is fairly reasonably priced
and works very well.
